courses to any appreciable degree. a I attain my object'bybuilding my wall of i 1 two parallel courses, preferably using hollow tile as .the building material. These courses are spaced apart so as to leave between them an air space 'ofsnbstantial width; and the courses are connected by bonding'members theflends of which are suppor'tedjin said courses, such bonding members being made of hollow tileand provided with transverse vertical intermediate their ends so 10- catedthat such webs will be supported on the inner ed 35 wall constructionfjlwit 'materialt 'd portions of said courses, and thus leave t eintermediate' air space unob structed except by 'longitudinaljwebs of. said bonding members. 7 fu'llhe details of my wall construction are 5' ings, in which: ,4 ig'. 1 shows .apersple' Fig. 2 is a-transverse se'ctionofmywall construction on 'the'plane of the line 2 of [built in accordance with my invention it is Figs. 1 and 3-"this view" al,so 'showing insulating material introduced-between-the two courses;

As mentioned, my wall consists of inner and outer courses a, b,' the material for'buildingwhich may be brick, but preferably I I use hollow tile.- The members of these walls are laid in the-usual way so as to break the joints. The 'wall courses are bonded todegree by the longitudinal webs 'f of the bonding tile or members c' bei ngjv illustrated in, theaccompanying draw I section of my out any insulating .poss'ess ample inherent strengt gether by. bonding members a, of which sufficient are used 'to a'flord the required stabil- 'ity. These bondingmembersconsist of tiles ate transverse webs of the bonding member's are so located that the'y will rest on the inner edge portions of the courses a and-b,

thus leaving the space at intermediate the courses unobstructed except to ainegligible er tical as shown. Iii this wa an amp e air space will'beleft between t e exteriorand interior courses, and the air spaces s0. provided may-be. left as such or the same may the webs be filled with d'ry'shavings, ground cork or other. insulating material, as diagrammatically indicated by g-in Fig. 2. The filling of the space betweenthe wallcourses is'especially of advantage 'where the building And when said space-is to be filled with in sulating material as mentioned, the arrangement of my bonding tile or, members is of great importance, because the bonding members willpresent so small a surface as not to interfere with the placing and packing of the insulating material, whereas, under other conditions, where there is a substantial interference with the placing'of the'insulat-' there is dan er vof'lea'ving empty air pockets beneath the onding members, andthus'correspondingly reduce the efiiciency of the insulating filling.

Itwillalso be noticed by those practical I in the art 'of wallconstruction, especially for b uildingsto used as cold storage plants, that while my construction is econo'micalpboth with respect to'the cost of material 'andthe' cost of buildin the walls and-.provide thorough insulation."

With reference'toi the strength of a wall further to be noted that, bythe construction tion'the edges'of the lon "tudinal webs of my bonding members aflor very little surface (in short, the surface provided by such webs is negligible) across which moisture canfollow from the outer course to the inner course of the wall.

I claim;

1'. A wall consisting of two parallel courses of wall members spaced apart so as to provide a space of substantial width between the courses. and transverse bonding members connecting said courses, the ends of said bonding inembers being supported in said courses, said bonding members being made of hollow tile consisting-of longitudinal vertical webs, transverse end webs and other transverse webs intermediate the ends, the intermediate webs being supported on the inner-edge portions of said courses, thereby leaving the air space between said courses unobstructed except by the longitudinal webs of said bonding members.

2. A wall consisting of' two parallel courses of wall members spaced apart so as to provide a space of substantial width between the courses, and transverse bonding members connecting said courses, the ends of said bonding members being supported.

in said courses, said bonding members be- 'ing made of hollow tile consisting of Ion tudinal vertical webs, transverse and We s,

and other transverse webs intermediate the ends, the intermediate webs being-supported- -'filling of insulating material insaid intermediate space.
